{"id":"CVE-2026-67623","summary":"Mistral Vibe \u003c 2.23.3 Arbitrary Command Execution via git fsmonitor Hook","details":"Mistral Vibe before 2.23.3 contains a remote code execution vulnerability that allows attackers to execute arbitrary commands by embedding a malicious core.fsmonitor hook in a repository's .git/config file, which is triggered when vibe invokes git status --porcelain without suppressing hook execution. Attackers can distribute or create a crafted repository containing a malicious fsmonitor entry to achieve arbitrary command execution with the victim's full privileges when any vibe command is run inside that repository.","modified":"2026-08-08T03:30:19.729278226Z","published":"2026-08-05T13:27:27.445Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-829"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67623.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67623.json"},{"type":"ADVISORY","url":"https://github.com/mistralai/mistral-vibe/releases/tag/v2.23.3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67623"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/mistral-vibe-arbitrary-command-execution-via-git-fsmonitor-hook"},{"type":"REPORT","url":"https://github.com/mistralai/mistral-vibe/pull/962"},{"type":"REPORT","url":"https://github.com/mistralai/mistral-vibe/pull/978"},{"type":"FIX","url":"https://github.com/mistralai/mistral-vibe/commit/68ff32e6a92e80a874c8153312f0aa8ae4955477"},{"type":"PACKAGE","url":"https://github.com/mistralai/mistral-vibe"},{"type":"EVIDENCE","url":"https://github.com/mistralai/mistral-vibe/issues/942"},{"type":"EVIDENCE","url":"https://therealcoiffeur.com/c111011.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mistralai/mistral-vibe","events":[{"introduced":"0"},{"fixed":"68ff32e6a92e80a874c8153312f0aa8ae4955477"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.23.3"}]}}],"versions":["v2.23.2","v2.23.1","v2.23.0","v2.22.0","v2.21.0","v2.20.0","v2.19.1","v2.19.0","v2.18.4","v2.18.3","v2.18.2","v2.18.1","v2.18.0","v2.17.1","v2.17.0","v2.16.1","v2.16.0","v2.15.0","v2.14.1","v2.14.0","v2.13.0","v2.12.1","v2.11.1","v2.11.0","v2.10.1","v2.10.0","v2.9.6","v2.9.5","v2.9.4","v2.9.3","v2.9.2","v2.9.1","v2.9.0","v2.8.1","v2.8.0","v2.7.6","v2.7.5","v2.7.4","v2.7.3","v2.7.2","v2.7.1","v2.7.0","v2.6.2","v2.6.1","v2.6.0","v2.5.0","v2.4.2","v2.4.1","v2.4.0","v2.3.0","v2.2.1","v2.2.0","v2.1.0","v2.0.2","v2.0.1","v2.0.0","v1.3.5","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.2","v1.2.1","v1.2.0","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.6","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-67623.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
